Cultured MDCK
en:wikipedia:epithelial cells
were stained for
en:wikipedia:keratin
, desmoplakin, and
en:wikipedia:DNA
. The stained cells were visualized by
scanning laser confocal microscopy
. The image shows how keratin
cytoskeletal
filaments are concentrated around the edge of the cells and merge into the desmoplakin which is located at
en:wikipedia:desmosomes
of the
surface membrane
. The network of keratin to desmosome to keratin linking the cells of an epithelial sheet is what holds together tissues like skin.
